1. AGS Polarized Proton Status January 25, 2011 Vincent Schoefer

2. Current performance 65% polarization with 1.4e11 intensity Emittances ~18  both planes at AGS flattop (jump quads off) – This is still large horizontally, even coming out the Booster

3. Tune jump quads – Calculation of jump times: Leif Gauss clock calibration scan: Leif Measurement of vertical intrinsic timing: Vincent – Effect on emittance (blowup and scraping) Coherence length and emittance blowup: Mei Closed orbit deviations from tune jump quads: Woody Horizontal scraping on J10 at AGS flattop: Vincent Momentum scraping at transition: Leif, Vincent – What are the ‘best yet’ times?

4. Optics Optics measurement and correction – High injection tune: Vincent – Survey results: Vincent ORM: Vincent Harmonic response: Leif – AGS model calibration: Nick, Francois – BtA model calibration: Nick, Keith Vertical BPM offsets at 9  – via orbit steerer drive term: Woody – via harmonic amplitude response to tune: Leif
